water based satin skirting board problems

[lidster]

Hi,
bought some mdf skirting boards and decided to paint them before fixing to wall.....but....the finish is terrible. ive used a water based satin.and from searching on here after ive painted it would appear that I have used an oil based undercoat and the 2 dont work well together.
I used Leyland Trade undercoat (says on the the tin -"ideal basecoat for gloss")
I then sanded lightly and applied 1 coat of Homebase Quick dry Satin.
It just looks all...."speckly" is the best way I can describe it.
Please help - how do I fix this? will try and post pic. Ive tried a 2nd coat on a few pieces and it has helped it a little bit but not really.
Any help much appreciated from the experts

You didn't wait long enough for it to dry. It works really well when you leave it a few days.

yeah I did read that on here but only after I had painted them. What is the best way to fix?
sand down and then apply undercoat again - then allow 2-3 days drying time?
OR
Sand down worst areas and keep applying Satin top coats?

thanks

Yes. Give it a sand so that there are no proud areas then re-satin it.

I was doing similar, but didn't have the time to wait between coats. So i stripped my mdf back and re-undercoated and painted with water based satinwood. 2 coats of each
Got really nice finish in less than half the time it takes to wait for the gloss stuff to dry.

Not helpful to you now i guess, but thought it worth mentioning.

We have cats and a dog so simply cannot afford the drying time without the huge chance of hairs getting all over the paintwork.
